Sounds like you ended up with water in your distributor cap maybe. Try opening
up the cap and drying everything off. Since a few companies sell de-greasing
chemicals which are designed to be sprayed onto your engine and then hosed off,
I don't think that hosing down a motor would damage it. I de-greased my Toyota
Mr2's engine a few years back, and as per directions, I wrapped up the
distributor cap with plastic and tried to avoid electrics with the water spray. 
After wards I had a rough-idle condition. This turned out to be a loose vacuum
   BTW the loose vacuum hose diagnosis was courtesy of a mechanic who came into
the place I was working towing a 968 in full racing regalia. I don't know what
class or anything else about racing, but he found that loose hose in about 10
secs. I spent hours pondering what the heck I had done wrong. :)
